Objectives:To observe the effect of rhGH in the treatment of chronic wasting diseases. Methods:Twenty two cases of chronic wasting diseases needing nutrition support were chosen,including 10 cases of COPD,12 cases of cerebral infarction or cerebral hemorrhage with decubital ulcer in recovery phase.They were in the age of 60～75,in combination with morderate malnutrition.These patients were divided into control group and experimental group.In the experimental group,rhGH(4.5 U/d) was given hypodermically for 10 days.Serum albumin,prealbumin,transferin,24 h urea nitrogen in urine,the surface area of decubital ulcer and mental state were monitored before and after the treatment. Results:In the experimental group,many nutritional indices were increased markedly,24 h urea nitrogen excretion was decreased,the healing of decubitus was faster and mental state was better when compared with control group. Conclusions:The rhGH plays an important role in improving the nutritional status and mental state in patients with chronic wasting diseases. On the base of supplying enough nutrients, rhGH can promote anabolism,reduce the excretion of urea nitrogen in urine, accelerate the healing of decubital ulcer and improve the prognosis.

Object:To find out college students' perceptions about counseling.Methods:By using a questionnaire about college students' view of counseling,875 college students of Zhejiang University from grade 1 to grade 4 were tested.Results:Most students acknowledged that counseling deals with mental issues and disorders. They were willing to help clients,and prefer counselors who are like their friends and family members.They agreed that counseling is helpful and,prefer one-hour sessions,which are free of charge.

Objective To study the detection and clinical signitlcanee of C reactivn protein(ClIP)and P-seleetin(P-sel)in patients with ulcerative colitis(UC).Methods The levels of peripheral blood ClIP and P-sel in patients with UC(n=53)and normal control group(n=35)were detected and the effects on disease severity were analyzed subsequently.Results The levels of blood CRP and P-sel in active phase group were significantly higher than those in catabasis group and normal controls group(P＜0.05);severe stage and medium stage were signiticandy higher than those in mild stage(P＜0.05,P＜0.01),severe stage was significantly higher than those in medium stage(P＜0.05);the blood level of CRP was positively related to P-sel in active phase group(r=0.638,P＜0.01).Conclusion CRP and P-sel were correlated with invasion and severity of UC.

Objective To investigate whether the μ- and δ-opioid receptors were involved in mediating the a ntinociceptive effect of opioid injection into the nucleus submedius (Sm). Methods Nociceptive behavior produced by subcutaneous injection of formalin (65 mmol/L, 50 μL) into the hind paw of the rat was assessed quantitatively using an automated movement detection system. The effects of morphine and selectiveμ- and δ-opioid receptor antagonists microinjected unilaterally into the Sm were determined in the awake rats. Results Morphine (31 mmol/L, 0. 5 μL) depressed the nociceptive behavior elicited by formalin, and this effect was antagonized completely by the selective μ-receptor antagonist β-funaltrexamine (β-FNA, 0. 4 mmol/L, 0. 5 μL) and naloxonazine (0.8 mmol/L, 0.5 μL), and partly by the δ-receptor antagonist naltrindole (0.4 mmol/L, 0.5μL).Administration of morphine into thalamic regions more than 0. 5 mm dorsal to the Sm had no effect on the nociceptive behavior. Conclusion Antinociceptive effects produced by opioid acting on Sm neurons are mediated mainly by μ-opioid receptors, and partly by δ-receptors.

25 mmHg) had no response to conservative management, and,therefore,had to be decompressed by invasive procedure,including 6 patients performed by decompression laparotomy,2 patients by laparoscopic decompression and 5 patients by ultrasound/computed tomography location and needle paracentesis drainage.These 13 ACS patients had obvious amelioration in physiological variables (hemodynamic,respiratory and tissue perfusion) after 24 hour post-decompression (P

Objective To observe the effect of polyethylene terephthalates (PET) coated with 58S bioactive glass on graft-bone healing.Methods The PET coated with 58S bioactive glass was used in experimental group,and uncoated PET was used as a control.The coating solution was made of 20％ bioactive glass powder and 80％ gelatin powder (by weight).In our vitro study,4×104/ml MT3T3-E1 cells were cultured in 24-well plates with the coated or uncoated PET,and the MTT and ALP were tested at 1,3,5 days to show the proliferation and the activity of the cells.The SEM and the X-ray photoelectron spectrometer were adopted to analyze the surface characteristics of the fiber.In our vivo study,24 skeletally mature New Zealand white rabbits were randomly divided into two groups,the 58S-PET group and the PET group.Both groups underwent a surgical procedure to establish a tibia-articular tendon-bone healing model.Mechanical examination and histological assay were taken to verify the coating effect in vivo.Results The 58S-PET group showed significantly differences in both the MTT and ALP tests at each time point (3,5 days) compared with the PET group.In the animal experiments,the maximum load increased by time in both groups.At 6 weeks,the load-to-failure was significantly higher in the 58S-PET group [(61.70±6.95) N]than that of the PET group [(45.21±9.78) N].At 12 weeks,the load-to-failure was also significantly higher in the 58S-PET group [(89.25±9.50) N]than that of the PET group [(71.38±6.26) N].In the histological assay,it was found that there was new bone formation in the indistinct interface between the graft and the host bone in both groups at 6,12 weeks,and a stronger binding was seen in the 58S-PET group than in the PET group.Conclusion The 58S-PET could enhance the proliferation and activity of the osteoblast and therefore promote the new bone formation and subsequently leads to a positive effect on tendon-bone healing.

OBJECTIVETo establish a general method of focal cerebral ischemia model in different varieties of mice.

METHODEach group of healthy adult KM and C57BL/6 mice were randomly divided into control group (n = 10) and MCAO group (n = 10). The mice in MCAO group were applied in the preparation of the MCAO model by intraluminal occlusion using monofilament. Twenty-four hours after operation,the neurologic function was evaluated,middle cerebral artery blood flow was monitored and the infarction volume was calculated by TTC staining, to evaluate the reliability of the model.

RESULTIn the MCAO group, the base value of the cerebral blood flow down of KM and C57BL/6 mice respectively was (81.65 ± 4.59)%, (83.68 ± 6.25)%. The neurological deficit score respectively was (2.30 ± 0.82), (2.50 ± 0.80). TTC staining can clearly show the infarction area, and relatively stable, 24 hours of the survival rate of KM and C57BL/6 mice were 100% and 80% respectively.

CONCLUSIONThe key link is the optimization and improvement of monofilament, temperature, anesthesia and so on. The modified intraluminal occlusion of MCAO using monofilament is a kind of reliable and simple method to establish experimental cerebral ischemia model in mice.

Objective To analyze the reasons of discarding as useless of ?-Se direct conversion digital flat panel detector (?-Se FPD). Methods (1) E-COM DR-2000CTM chest system, with high frequency X-ray machine made by CPI company of Canada, the X-ray tube made by VARIAN company of America and Direct Ray-1000 ?-Se FPD made by DRC company of America. (2) 50 cases were collected rondomizedly, each had 4 pieces of chest image and were analyzed by two experienced radiologists and two technicians. Results After about 14 months with 30,000 times exposure efficacious, some damage lines and points appeared in the detector. After about 34 months with 70,000 times exposure efficacious, a damage region (area is 6.7in*0.95in ) existed, this reduced the images' quality and at the end the detector was discarded as useless. Conclusion The ?-Se FPD needs maintenance and monitoring working circumstance.
